Device comment
• CPU modules other than the High-speed Universal model QCPU and Universal model Process
CPU:
74 + 8 + (total comment data size of each device)
• High-speed Universal model QCPU and Universal model Process CPU:
74 + 72 + 8 + (total comment data size of each device)
Comment data size per device = 10 + 10240 × a + 40 × b
• a: Quotient of ((number of device points)/256)
• b: Remainder of ((number of device points)/256)
Initial device value
• CPU modules other than the High-speed Universal model QCPU and Universal model Process
CPU: 66 + 44 × n + 2 × m + 8
• High-speed Universal model QCPU and Universal model Process CPU: 66 + 44 × n + 2 × m +
72 + 8
• m: Total number of device points set to the initial device value
• n: Number of settings of the initial device value
User setting area Setting value when formatted (0 to 15K)
File register 2 × (number of file register points)
Sampling trace file
362 + (number of word device points + number of bit device points) × 12 + (N1 + N2 + N3 +
number of word device points × 2 + (number of bit device points/16) × 2) × the number of traces
(total number of executions)
• Apply the following values to N1 to N3 according to the items selected under "Trace additional
Information" on the Trace condition settings window. ( Page 187, Section 3.14 (8) (b))
• N1: When "Time" is selected, apply "4".
• N2: When "Step no." is set, apply "10".
• N3: When "Program name" is selected, apply "8".
Device data backup file Setting value when formatted (2 to 1024K)
Module error collection file 76 + (64 × (value set for the number of storable errors))
Local device
*4
70 + 6 × (set device type) + (Am + Av + B + Ct + Cst + Cc) × n
• Am, Av = (((a1 + a2) 16) -a11161× 2
• B = b × 2
• Ct, Cst, Cc = ((((c1 + c2) × 2) 16 - ((c1 × 2 + 1) 16) + 1) × 2 + c2 × 2
• Am, Av: Save area sizes of M (internal relay) and V (edge relay), respectively
a1: Start device number of M or V
a2: Number of points of M or V
• B: Save area size of D (data register) and Z (index register)
b: Total number of points of D and Z
• Ct, Cst, Cc: Save area sizes of T (timer), ST (retentive timer), and C (counter), respectively
c1: Start device number of T, ST, or C
a2: Number of points of T, ST, or C
• N: Number of programs (only the ones using local devices
*5
)
